Re: Anyone Blow a 6.0 Head Gasket Yet?

I'll second that. Layered steel head gaskets do not "blow" the way composite gaskets do. Coolant really cannot leak into the cylinders because the cooling system does not have enough pressure to do so.
There is still enough pressure on the gasket to form a seal. When the head gaskets fail to seal effectively, they leak combustion into the cooling system and force coolant out of the de-gas bottle. You may have steam coming from under the hood but no billowing smoke.

Does coolant blowing out of the de-gas bottle usually signal a head gasget issue? It happened to me recently. Also, what does a dealer do to test for head gasket issues?
